With the accelerated pace of life and the progress of the times, the term fatty liver is becoming more and more familiar to people. When fatty liver appears around us, some people are trembling, but there is no big problem; some people do not take it seriously, but it eventually becomes a scourge. Faced with fatty liver, which we do not understand, how to face and treat it properly? Fatty liver refers to the deposition of triglycerides in liver cells due to obesity, chronic high-fat diet, weight loss, persistent malnutrition, disease, medication, etc. This condition can sometimes cause symptoms such as weakness and fatigue, loss of appetite, and pain in the upper right abdomen. But more often there are no characteristic manifestations. It is only detected during physical examination and is highly insidious and confusing. Clinically, fatty liver is usually divided into alcoholic fatty liver and non-alcoholic fatty liver. In fact, it can be further subdivided according to the etiology. It includes alcoholic fatty liver caused by alcohol addiction; obese alcoholic liver caused by obesity and high-fat diet; metabolic fatty liver caused by malnutrition or extreme weight loss. It can be further subdivided into fatty liver due to alcoholism, fatty liver due to obesity and high-fat diet, fatty liver due to malnutrition or extreme weight loss, fatty liver due to drugs that affect protein metabolism, fatty liver due to other diseases such as diabetes, etc. As we can see, fatty liver is not exclusive to alcoholics and fat people, but it is also possible for normal people to develop fatty liver. There are different types of fatty liver and there are some differences in treatment. For example, alcoholic fatty liver caused by alcoholism, and obese fatty liver caused by obesity and other reasons. The main treatment measures are to adjust the diet, change the bad habits and physical exercise. However, for metabolic fatty liver, whether it is malnutrition or excessive weight loss, all these causes cause a large accumulation of ketone bodies on the liver for gluconeogenesis. At this time, we need to adjust the patient’s diet according to the specific situation of the patient, and strive to restore the normal metabolic state of the liver. If necessary, we can take some oral liver-protective drugs. If we find that the patient is suffering from drug-related fatty liver because of taking some anti-tumor drugs or abusing some drugs of unknown origin, then we need to make specific analysis according to the patient’s condition and make timely adjustments to the drug treatment. At the same time, detoxifying and liver-protective drugs such as reduced glutathione should be used for treatment. In some patients, fatty liver is secondary to certain diseases, such as diabetes mellitus. In this case, we need not only to protect the liver, but also to cooperate with the specialist to make reasonable treatment for the primary disease. In the early stages of fatty liver, there are not really any obvious symptoms. Therefore, there is a view that it is a rich disease and is not harmful to the human body. However, this is not true. In the early stage, fatty liver does not show any changes in liver function and is sometimes detected only during ultrasonography. However, if the fatty liver progresses gradually, steatohepatitis may develop. The patient’s transaminases begin to rise and there may be fatigue, loss of appetite, vague pain in the liver area, and some other symptoms. In both cycles, fatty liver is reversible. Through dietary modification, lifestyle modification. The patient can recover quickly. Patients can recover quickly. But if it is allowed to progress. Then liver fibrosis will appear. The patient’s symptoms will further worsen. More serious cases lead to fatty cirrhosis. At this point, treatment will be very difficult. In the face of fatty liver, which should not be underestimated, we need to have the right attitude and concept. To do without disease prevention and control, with disease treatment. Advocate a high protein and low fat diet, eat more fruits and vegetables, eat less and move more without drinking, and use drugs carefully without staying up late. If you have a mild to moderate fatty liver, on the premise of doing the above, you should promptly consult a doctor and make targeted treatment according to your different conditions. Generally speaking, the treatment effect is very good.
